Fish in Greenland consume more jellyfish than previously assumed, researchers discover
For a long time, scientists assumed that jellyfish were a dead-end food source for predatory fish. However, a team from the Alfred Wegener Institute together with the Thünen Institute has now discovered that fish in Greenland waters do indeed feed o.....»»
New cobalt complex triggers ferroptosis in cancer cells
In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells in certain tissues, for exam.....»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
A hopper could explore more than 150 km of Triton"s surface in two years
Neptune's largest moon, Triton, is one of the most biologically interesting places in the solar system. Despite being hard to reach, it appears to have active volcanoes, a thin atmosphere, and even some organic molecules called tholins on its surface.....»»
Wobbly molecules closer look with a new theoretical framework
